Crooked Teeth and a Bad Bite

How's your occlusion today? When your jaws meet nicely and teeth are configured properly in your jaw, that's occlusion. When the fit's awry, it's called a malocclusion .

About 2,000,000 Americans know malocclusion inside and out. So what's wrong with a little overbite? For 20% of us, it's a handicap, for 5%, it's a physical and mental hardship. That's why there's orthodontics.

The gist of jaws

The upper jaw, or maxilla, is part of the skull and it doesn't move. In children, the maxilla is joined at the root of the mouth by soft tissue that grows into one bone mass by about age 17. Our upper teeth are a little bigger than the lowers. We call the lower jaw the mandible. When the maxilla and the mandible work properly, they chew, grind, and tear our food, facilitate normal speech, swallowing, and basic oral health. When your jaws don't align well, you may not be able to eat, breathe or communicate normally.

Getting the bite right

Orthodontic theory, and attempts at bite correction, can be traced to ancient Greek and Roman cultures. But until dentists could agree on the problem, each rigged his own correction device. Some of these 19th century "designer" orthodontic appliances were fanciful, some merely crude.

The early orthodontist Edward Angle classified occlusions into three types. His principles are still the standard today.

• Class I occlusion is a "normal" bite. Since there is argument what "normal" is, Class I could be defined as a jaw/bite relationship that seems to be okay and doesn't cause any problems, although there may be some tooth crowding caused by eruption of extra teeth or missing teeth.
• Class II brings us to true malocclusions, in this case, the buckteeth of Bugs Bunny fame. It's certainly more amusing as a cartoon than reality though. Class II lower jaws are usually small and crowded. Along with a protruding upper jaw, the chin recedes. Children with Class II bites, and adults, for that matter, seem especially subject to social derision. Aside from problems with keeping teeth clean, Class Iis can expect cruel jokes.
• Class III malocclusions are relatively rare (5%)and may include a jutting lower jaw and lower teeth that close in front of the uppers (think Dick Tracy). Treatment is complex, and may require bone surgery.

In any case, seeing your dentist on a regular basis is very important. In the case of Class Iis and IIIs, seeing an orthodontist could make a big difference in your self-esteem and make your life much easier.

With more adults seeking treatment their parents couldn't afford when they were youngsters, this is a very exciting time in orthodontics—we have a world of new orthodontic materials that work better and faster.

Heavy metal bands? Most of us have heard the news about braces. They're lighter, smaller, easier to clean—dare we say it—almost comfortable. Plastics and bonding adhesives mean no more heavy metal bands around teeth. Wire and brackets can be "super-glued" directly onto the teeth (Look, Ma, no bands!).

NASA's missile technology has given us Nitinol, a "memory" metal that retains its shape better than stainless steel. Arch wires made of Nitinol exert a light, steady force that stands up to the push and pull of orthodontic appliances. And lingual braces, glued to the back (tongue side) of the tooth, are proving effective in closing moderate gaps. It's like having invisible braces.

A new breed of patient

The best part of new orthodontics for your orthodontist, though, is a willing, and eager patient. Home care is critical to any orthodontic treatment plan. Careful, constant cleaning, wearing your retainers, and avoiding foods that make a mess of all the handiwork is a must. Most adult patients appreciate the investment of time and energy and tend to go about home care with vigor.

How Malocclusion - or Bad Bite - Can Be Fixed by Braces for Teeth

It is ironic that one of the most common dental disorders is also the most neglected. The way the teeth fit together when the jaw closes and chews is of profound importance to the long-term health of your teeth.

If surfaces of the teeth interfere with how the jaw moves, the teeth can be worked loose or the enamel can be worn away. The muscles that move the jaw are very powerful and can do major damage to the teeth when the biting surfaces don't fit together properly.

The problem can be compounded if teeth interfere with functional muscle patterns, the jaw muscles will attempt to "erase" the part of the tooth that interferes by grinding against it all the more. This can lead to even more severe wear or it may crack off a cusp or split the tooth. Or it may loosen the tooth or cause it to move out of alignment. The excessive muscle activity often results in pain in the muscle itself. All of the jaw muscles can become sore including the temporal muscles that are the source of many so-called tension headaches.

Some excessive muscle activity may be caused by emotional stress. But with some special exceptions, damage done by stress induced grinding and clenching can be minimized to a manageable level by equalizing the biting surfaces that are in conflict with jaw movements. Proper fitting of braces for teeth can solve the problem by gently moving the teeth into a more optimal position.

The power of the jaw muscles may surprise you. Some people can exert over 900 pounds of compressive force with their jaw muscles so you can imagine how much damage such force can do when you close into a single tooth and then work it from side to side. The effect is very much like working a fence post loose as the bone around the root breaks down. If you can put your finger on any tooth in your mouth, and then squeezing your teeth together causes the tooth to move, you can be sure that it is just a matter of time before there will be a problem with that tooth.

Sometimes the muscle forces that work the tooth sideways stimulates bone around the root to build up and become stronger. When that happens, the tooth actually bends in its socket and this creates a microscopic chipping away close to the gum line to form a deep groove in the tooth. This is called an abfraction. These deep grooves at the gum line are often mistaken for toothbrush abrasion, but scientists have shown us that the grooves are actually the results of bending of the tooth in its socket. These grooves can lead to much sensitivity in those teeth because the opening into the tooth exposes nerves that can be exquisitely sensitive. Correction of the bite with Dental Braces to remove excessive lateral forces on the teeth in most instances either eliminates the sensitivity completely or reduces it to a much more acceptable level.

Patients should be aware that much confusion surrounds the importance of a harmonious bite, including many misconceptions that have been fostered by flawed research that has failed to properly relate the bite interferences to the position and condition of the temporomandibular joints. Knowledgeable clinicians, however, are very much aware of this relationship and can achieve excellent results with braces for teeth that will help make both your teeth and your jaw muscles more comfortable by bringing your whole biting into harmony.
